A refrigerator should be kept at a temperature between 34°F and 40°F (1°C to 4°C) to ensure food safety and freshness. The ideal temperature commonly recommended is around 37°F (3°C), which is cold enough to slow bacterial growth without freezing food
. Key points on refrigerator temperature:
- The USDA and Food Standards Agency recommend keeping the fridge at 40°F (4°C) or below to prevent harmful bacteria growth
- Setting the fridge around 37°F (3°C) is optimal for preserving food quality and safety
- Temperatures below 34°F risk freezing some items like milk or soda, while temperatures above 40°F increase the risk of food spoilage and bacterial growth
- It can take up to 24 hours for the fridge to stabilize after adjusting the temperature dial
- To accurately measure the fridge temperature, place a thermometer in a glass of water inside the fridge for several hours and then check the reading
For freezers, the recommended temperature is 0°F (-18°C), which effectively stops bacterial growth and preserves food for longer periods
. In summary, keep your refrigerator between 34°F and 40°F, aiming near 37°F for best results, and ensure your freezer is at 0°F for optimal food safety and preservation.
